Long time LED Flasher circuit diagram

Today Im going to going to show you a very wonderful schema diagram .The special thing of this schema is this schema can light up a LED more than the normal time.Sometimes it will light up our LED more than one month.so I suppose this would be a good news for you guys.Here I have used very common Transistor 2N3904.When I was making this schema I turned about  20 turns around the toroid. the wire was a small schema wire.    

 




# Build this schema on a PCB


 # Dont use more than 1.5V
